Title: Process and apparatus for the impregnation of articles
IPC: B05C11/10
Filed: 1983-10-14
Abstract: A process and an apparatus are described for the impregnation of articles with liquids, especially for the impregnation of wooden parts with creosote. In this process the impregnation vessel in which the articles to be impregnated are arranged is filled with the impregnation liquid from a container, after which additional impregnating liquid is injected into the vessel from a separate measuring vessel. Thereafter the impregnating liquid is let out of the impregnation vessel, and after the following vacuum phase the residual quantity of impregnating liquid is fed back to the measuring vessel. The quantity of liquid taken up by the articles can thus be precisely determined, based on the quantity consumed in the measuring vessel or by the quantity which has to be topped up in the measuring vessel to reach the previous state. Different kinds of control or regulation possibilities for the process are offered. <IMAGE>
Patent DE-3337903-A1 (DE)
Title: Catalyst arrangement
Inventor: REIF GERHARD
IPC: F01N3/035
Filed: 1983-10-19
Abstract: A catalyst arrangement for reducing and oxidising pollutants in hot oxidising exhaust gases has, with respect to the direction of flow of the exhaust gas, firstly an oxidising region (10) and subsequently a reducing region (11). The region favouring oxidation is preferably formed as a catalyst filter (10). As a result it is possible to filter out, for example, soot from an exhaust gas and to burn it to carbon dioxide. As a result of this consumption of oxygen in the oxidising exhaust gas, only a more weakly oxidising exhaust gas passes into the reducing catalyst region (11), which can operate particularly effectively as a result. The catalyst arrangement is particularly suitable for converting pollutants in the exhaust gases of diesel engines. <IMAGE>

Title: Method and device for producing photographic copies
Inventor: HAKAMADA HARUO
IPC: G03B27/46
Filed: 1983-11-30
Abstract: A method and device for producing photographic copies or prints are specified, by means of which all photographs which are taken on a photographic film can be printed or copied in the form of copies or images (B) on a carrier (A). These carriers (A) can in this case simultaneously form the individual sheets of an album. For this purpose, a light source (1) with an optical system (2-6) connected downstream is provided, by means of which the photographs are projected onto the desired location on photographic paper (7), and the images are produced there. In this case, both the lens (5) and the photographic paper (7) together with its associated carrier can be movable or displaceable, in order to obtain the desired arrangement of the images on a sheet with photographic paper (7). In particular, it is possible in this way to obtain an arrangement of images from a disc film (14) in which the respective images are arranged on the circumference of a wheel-shaped disc. In this case, it is possible to avoid blurring of the images due to graininess of the film material, since in any case only a slight enlargement is employed when producing the photographic copies. <IMAGE>

Abstract: The invention relates to a jug, in particular an insulating jug, consisting of a housing which receives an insulation insert and has a handle, a filling or pouring opening and a lid which bears a closure slide which interacts with the filling or pouring opening and is displaceable between a closed position and an open position by means of an adjustment mechanism which is guided with the handle through a passage out of the lid, the closure slide being prestressed by the force of a spring in the direction of the closed position and being retainable in the open position counter to the force of the spring by the adjustment mechanism, and the adjustment mechanism being formed by a first lever which extends approximately horizontally in the lid, is guided laterally out of the lid, and engages directly or indirectly on the closure slide. The purpose of the invention is to design the jug in such a way that the adjustment mechanism requires only a relatively small adjustment path in the region of its passage through the circumferential wall of the lid for sufficient opening of the filling or pouring opening and maintaining easy handling. This is achieved in that the first lever (33) is in drive connection with the inner lever arm (44) of a second, two-armed lever (34) which is mounted in the lid (5) near to the circumference, engages through the passage (52), and whose outer lever arm (57) ...

Title: Method for controlling a heat transfer station
Inventor: KIRNER HERMANN
IPC: G05D23/19
Filed: 1984-07-10
Abstract: In a heat transfer station having a primary circuit (I), heat exchanger (5) and secondary circuit (II), the respective temperature of the heat medium is measured, both in the return line (2) and in the feed line (1), via temperature sensors (15, 18). Both measured values are fed to a controller (19), the return temperature representing the controlled variable and the feed temperature serving as reference variable for a desired-value displacement. The primary rate of flow in the heat exchanger (5) is set by means of the output signal of the controller (19). Since the feed temperature is guided by the weather, a weather-guided control of the feed temperature in the secondary circuit (II) is also achieved in this way. <IMAGE>

Title: Control arrangement for a hydraulically operated consumer
Inventor: THOMSEN SVEND ERIK
IPC: F15B11/00
Filed: 1984-10-03
Abstract: A control arrangement for a hydraulically operated consumer (1) is to be improved. The consumer (1) can be supplied with pressure fluid on the inflow side from a pressure-fluid source (3) via a pressure-compensation valve (5), a connecting line (11), a valve (7) on the inflow side and a consumer line (12) on the inflow side. A signal line (18) carries a signal pressure (PS) which acts on the pressure-compensation valve (5) in the same direction as a spring (28) and in the opposite direction to a compensation pressure (PK) tapped at the connecting line (11). The signal line (18) has a first connection branch (19) connected to the consumer line (12) on the inflow side, a second connection branch (20) connected to the connecting line (11), and a third connection branch (21) connected to the return line (16). To form a pressure-divider arrangement (26), a restrictor (22, 23, 24) is arranged in each connection branch. In this way, the transient phenomenon can be rapidly stabilised while largely maintaining the feeding independence. <IMAGE>

Title: Hydraulically damped elastic bearing, especially for the propulsion engine in motor vehicles
Inventor: EBERHARD GUENTER DIPL ING DR
IPC: F16F13/26
Filed: 1984-10-05
Abstract: The subject-matter of the invention is a hydraulically damped elastic bearing for engines and machines, which bearing contains in its damping device a flexible membrane which is clamped in between rigid supporting plates and controls the free flow cross-section of a restrictor-overflow hole. The diaphragm is in this case clamped with a small amount of axial play in order favourably to influence the acoustic behaviour of the bearing via such a free movement. According to the present invention, the axial play of the diaphragm can be varied at will from outside the bearing and, in the extreme case, can be reduced to zero. The invention thus creates the preconditions for close matching of both the damping of the bearing and of its acoustic properties to the respectively prevailing conditions.

Patent DE-3445417-A1 (DE)
Inventor: BRUGGISSER WALTER
IPC: H02P9/00
Filed: 1984-12-13
Abstract: Rotating frequency converters are used for the transmission of electrical power in the band from 8 MW - 90 MW from a grid system (1) at 50 Hz or 60 Hz into a railway network (2) at 162 DIVIDED 3 Hz or 25 Hz and vice versa. The starting device for the synchronous machine (5) of a frequency converter group (3, 7, 5) allows the starting of the synchronous machine (5) from 0 Hz up to the rated speed, corresponding to a rated frequency, within 8 - 10 minutes, in 3 steps, by means of a direct converter (4) without a special starter transformer and without a starter resistor, i.e. with reduced equipment complexity. At the same time, high rotor voltages when stationary and on switching, and switch-on surges on switching-over and switching the frequency converter group to the two AC networks (1, 2), are reduced. Initially, the direct converter (4) is connected to rotor windings of an asynchronous machine (3), while the stator windings of the asynchronous machine (3) are short-circuited. The adjustable frequency (fX) at the output (A) of the direct converter (4) is increased from 0 Hz to above 20 Hz. As a consequence of the rigid coupling (7) of the rotor of the asynchronous machine (3) to the rotor of the synchronous machine (5), its stator frequency increases to about 40% of the rated speed. The direct converter is then switched over to supply the stator winding of the DC-excited (6) synchronous machine (5), and the frequency (fX) at the output (A) of the direct converter (4) is increased from 40% to 104% of the rated speed. Thereafter, the direct converter (4) is switched over onto the rotor winding of the asynchronous machine (3) again, the latter is synchronised to the grid system three-phase network (1) at the outlet, and is connected thereto by means of a switch (S1). Thereafter, the synchronous machine (5) is synchronised by means of slip regulation and is connected to the railway network (2). <IMAGE>

Title: Integrated motor/air pump arrangement
Inventor: IO SHINICHI
IPC: F04B45/04
Filed: 1985-06-13
Abstract: In an integrated motor/air pump arrangement the air passed from the environment into a servo-drive chamber or the air discharged from the servo-drive chamber into the environment flows through the motor which is accommodated, together with the air pump arrangement, inside the pump casing. The air flow generated by the air pump arrangement is able to cool effectively the motor driving the air pump arrangement, as a result of which any overheating of the motor can be avoided. The air pump arrangement in particular comprises a connection valve for opening/closing a connection line which connects a servo-drive chamber to a pump chamber; in addition, air flow valves for opening/closing air flow bores are present within the pump arrangement. The connection valve is closed if the air flow valve is open and vice versa, in order to discharge air periodically from the servo-drive chamber into the environment or to pass it from the environment into the servo-drive chamber.
